CHALKING DEVICE FOR BILLIARD-OUES.

Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed April 25.1907. ser al No. 270,325.

' made a certain new and useful Invention in Ohalk'ing Devices forliilliardd ues; and I declare the following to he a lull. clear, and eLet description oi the same, such as will enable others skilled in theart to which it appertains to make and use the invention, reference ortigures of rel'orenee marked thereon, which lorm a part of thisspeeilieat ion.

Figure l. is a perspective view of the invention. Fig. 2 is a centrallongitudinal section of the samo. :l ig. 3 is a similar view showing thechalk and holder separately. Fig. 4 is a similar view illustrating theuse oi the limitation device for the chalk.

The invention has relation. to holders for billiard chalk. and itconsists in the novel construction and eombi nations of parts ashereinafter set forth 'lhe obj eet of the invention is toprovide aholder from which the chalk cannot be removed until it is worn out orbroken; to save chalk, and time in serving the same; to l'acil itateproper a ppl ication ol' the chalkto end of c te, and to keep the chalktree from dust without ii'iterlering with its ready applieat ion.

in the accompanying drawings illustrating the invention the letter a,(l(. nates the holder; I), a piece ol' chalk therein; a. a piece ofpaper or labric surrounding the chalk, and 1/, a suspension cord.

The holder (1, consists of a cylindrical body, having a cylindricalcavity extending upward therein, the bottom being open and having arounded margin, as shown. The cavity is made deeper than the length ofthe chalk block, so that when the latteris in place in its seat therewill b ea chamber 0,. above it in the cavity, said chamber beingcontinuous with the seat portion and of the same diailletel. The sidewalls ol the holder body, which is usually made oi wood are designed toclasp the chalk by their inherent elasticity, and in order that this maybe more el'l'ectively accomplished they are made rather thin ol' thesame thickness throughout and the holder and the cavity therein oiconsiderably greater length than the chalk cylinder. Inasmuch as theelasticity of the side walls of the holder is of limited character, whenthe chalk cylinder is forced into its seat, so that its outer end liesslightly Within the outer end of the seat, it is dillicult to force itfarther into the seat. In practice an effectual stop is thus providedagainst i'urther movement of the chalk within the seat. The holder andits seat for the chalk is made cylindrical in form. to obtain an evenexpansion of the thin side walls and to avoid splitting such Walls.Through the center of the top is made an aperture f, through which thesuspension cord is passed, its lower end being knotted as at suchknotted portioi'i being secured and held in a tapered enlargement f, ofsuch aperture which prevents the knot from becoming loose or cut bysharp corners and keeps it out of the Way.

The device being suspended by attachment of the upper end oi the cord toa screw eye in the ceiling, or otherwise, is always in position for use,and the chalk being covered in by the holder above and at its sides isprotected l'rom dust. The holder is of suliicient length to suit thefingers in applying the chalk, and the rounded edge oi the opening ofits cavity serves to prevent injury to the cue tip.

When the chalk is worn out the shell thereof may be broken and knockedinto the inner clearance chamber l'rom whence the pieces thcreol willdrop outv In order to properly adjust the chalk in position and preventit from being placed too deeply in the holder,

well as to maintain the clearance chamber 0, a limitation device, suchas a transverse pin h, extending across the cavity at the top of thechalk seat portion, may be employed, although this is not consideredessential.

Having thus described my invention, what I claim and desire to secure byLetters Patent is l. A ehulk holder for use in playing billiardsconsisting ot a eylimlri-t'orm body having a central cylindrical cavityoi. the same dimensions throughout and consisting of an outer chalkseat: portion and an inner clearance chamber, the. side walls of suchbody being of thin elastic character having the same thicknessthroughout.

A chalk holder for use in playing billiards consisting ot a e\'liinlri-l'orni body having a central cylindrical cavity, of the samedimensions throughout and consisting of an outer chalk seat; portion andan inner clearance chainher. the side walls of such holder being of thinelastic character having ,he same thickness throughout, said body havingan end wall provided with a central perform tion having a taperedenlargement; at its inner end leading into such clearance chamber, andan attachment cordextendiug through such perforation and having a knotand its stop end located within such tapered enlargement.

in testimony whereof I atlix my signature, in presence of two witnesses.
